I have not been on htis site much. Several years ago, Dr. Scally's position was that HCG was not necessary for those on TRT? I have used HCG for much of the 15 years I have been on TRT. I believe it has helped maintain both testicle size and, importantly, libido and possibly sense of well-being. Can anyone tell me whether many, or any, TRT docs use HCG as part of the protocaol? Have others in my situation found that HCG helps libido or sense of well-being? Thanks
